Cascade Reaction and Synthesis of Bicyclo[2,2,2]octenones
Abstract
During study on the remarkable cascade reaction for synthesis of compound 1, the neo-caged scaffold 2 with a heterocyclic bicyclo[2.2.2]octenone moiety and two new allyl substituted xanthones 3, 4 were obtained besides the known caged scaffold 1. The probable reaction processes were also elucidated in this paper.
